Whenever you hear someone say "all politicians lie", you can bet that they are helping the politicians that are the biggest liars by implying they should be put in the same group as the most honest politicians. And most of the time it's Trump they are trying to defend.
There is no such thing as an honest politician these days to be frank. I want Harris to win over Trump, but I do not believe for a second that she is an honest politician at all. She is simply a better choice when compared to Biden and Trump.
However, all of these options suck. Even Obama seems like a proper option when compared to these three in my opinion.
